Here is part two of Curse's video preview:

Conjecture time!

For the moment, my guess is that this is both our new champion with " gravity influencing" abilities ( she can pick up minions, fling people around,etc ) and Dark Sovereign - an assumption based solely on her passive being quite different from what we've seen so far. It certainly fits Morello's bill of "exploring new game play mechanics".

At any rate, I wouldn't get too riled up about the quick succession of champion releases or anything, this situation is very similar to the one with both Hecarim and Varus being playable at PAX East, yet that one didn't speed up the release date of Varus at all.

The real question though, the one I think a lot of people share, is... what is the lore behind our mysterious new champion? A lot of fans are pulling for this to be the reveal of Kassadin's daughter, who, in the lore, was captured by Malzahar and imprisoned within the Void. Could this be her big return?

Looks interesting, true. But I expected more when i heard 2 weeks ago about that gravity-controlling champ they would present us at gamescom. But we will see, overall I never got disappointed by RIOT :D

And Kinesis uses the mechanics (including a direct copy of the lift and throw unit mechanic) of a hero in the old Warcraft 3: FT mod Aeon of the Zenith. Whats new? The "X hero is just X" posts are pointless, because any time theres an innovative mechanic in a moba, one of the thousands of Warcraft 3 mods probably had the mechanic first.

In reference to her, her force push skill looks interesting, especially kicking those orbs for stuns. She'll reward good play, thats for sure.

Really small typo in the last paragraph 'captured my Malzahar' - shouldn't it be 'by'? :p

Other than that: awsome champ. Except her passive will will most likely benefit Q first as it's her main usable skill (cd, dmg wise etc). But I really like the thinking behind making her more dangerous with levels :3

They're not ripping of Kinesis, Kinesis used telekinesis to lift up trees and creeps and use them to attack enemies, Syndra uses balls to zone and she uses them to attack, it's different. So no. Riot did not rip off Kinesis. Can Kinesis spawn balls to zone? Can he use them to attack and launch them? Can she lift up almost everything around her? No. So they never ripped HoN off :)

Now I want that champion. URGENTLY. The only Mages I actually think are worth it: Probably gonna be in the zone of my best mages, alongside my main and best played Malzahar, and my second one, Kassadin. What a coincidence... I have a passion for arcane, magical, floaty and pure nuker mages. <3

I found it extremely irritating. It's not difficult to take a second to experiment with how your abilities function, even if you can't read the descriptions.

I'm super excited about this champion (femme fatale mages are generally my favorites), so I'll be waiting for a higher resolution video of someone that actually attempts to showcase her appropriately, versus just fumbling around and pressing random keys.
